You draw an indelible mark on the subject and state some behavior on the part of the subject that will activate the mark. When activated, the mark curses the subject. Typically, you designate some sort of quest that activates the mark if failed, but you can pick any act you please. The effect of the mark is identical with the effect of bestow curse.

Since this spell takes 10 minutes to cast and involves writing on the target, you can cast it only on a creature that is willing or restrained.
